Meanwhile, the Cromwell hotel — the redo of Bill's Gamblin' Hall — will welcome its first overnight guests on Wednesday.

With fewer than 200 rooms, the boutique property is dwarfed by its super-sized neighbors at Las Vegas Boulevard and Flamingo Road: Bally’s, Bellagio and Caesars Palace.

The Cromwell's small size, combined with rooms featuring a mix of classic and contemporary French design, is among its selling points. Room rates, priced on May 15 (so they may have changed), varied from $239 on opening night to $459 on May 24.

The hotel’s hub is sure to be on the roof, which will be home to Drai’s day and night club. It will boast five pools and 10 bungalows, each with its own restroom and shower and commanding views of the Strip 11 stories below.

Admission is free.

Fun in the sun can create a mighty thirst, so the mixologists at Monte Carlo have crafted a quenching beer cocktail to be served poolside. The banana guava shandy contains Absolut Miami vodka, Briottet crème de banane liqueur, guava nectar and Shock Top Belgian White Ale.
